# Polym vs Cognify

The clearest difference is ads: Cognify at none against Polym's shown. Cognify also leads on review sentiment (100% vs 70%) and rating (5.0 vs 4.6). Polym's advantage is update cadence (every 11 days vs monthly) and ratings volume (36 vs 5). On price, in-app purchases, monetization model and iOS requirement there is nothing between them.

Both are free to download. Polym sells 7 in-app purchases, starting at $7.99 per month and Cognify sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Cognify holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Polym has 36 ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 70% of Polym's written reviews are positive against 100% of Cognify's.

Polym ships an update every 11 days, Cognify monthly. The most recent releases landed on October 6, 2026 and September 29, 2026 respectively.
